EXERCISE Fill in the blank 1 DNA replication takes place during the 2 The enzyme primase builds short RNA segments called polymerase can build the complementary strand of DNA 3 Because DNA synthesis proceeds in the 5 to 3 direction the pieces called Okazaki fragments Respond to the following based on your reading portion of the cell cycle 5 required before DNA is replicated in short 4 What s DNA replication and why is it an important part of cell division 5 Explain what semiconservative DNA replication is and how it is different from conservative and dispersive models of DNA replication 6 Name the five major enzymes involved in DNA replication and briefly explain their roles in the process 7 Discuss the differences between eukaryotic and prokaryotic cell division and DNA replication 1 DNA replication takes place during the interphase portion of the cell cycle 2 The enzyme primase builds short RNA segments called primers required before DNA polymerase can build the complementary strand of DNA 3 Because DNA synthesis proceeds in the 5 to 3 direction the lagging strand is replicated in short pieces called Okazaki fragments 4 DNA replication is the process by which a molecule of DNA is duplicated to produce two identical DNA molecules Which accompanies cell division because any time a cell divides an entire copy of the organism s DNA must be made to ensure that the daughter cells have identical DNA as the rest of the body s cells Without DNA replication some daughter cells would not contain DNA and not be able to further divide DNA replication is essential for the cell growth cell repair and reproduction in organisms
